Duct Flange Gasket (em inglês)
A closed-cell EPDM rectangular gasket that compresses between mating duct flanges to close air-leak paths around the joint.
- Closed-Cell EPDM
- Four Bolt Holes
- Rectangular Air Opening
- Compressible Cut Edge
Introdução do produto
The gasket is cut from thick black closed-cell EPDM with a central rectangular air opening and four corner bolt holes. Its broad perimeter compresses between mating duct flanges while the cellular edge accommodates minor surface variation.
Características-chave
Four holes align with a simple corner-bolted flange pattern.
A broad sealing land distributes compression around the opening.
The resilient cut edge accommodates minor flange irregularity.
Preocupações do produto do cliente
Rigid or uneven duct flanges require a compressible interface to prevent leakage around the air opening.
Minor flange waviness leaves leakage paths.Compressible EPDM conforms to local surface variation.
Misaligned holes distort the gasket during assembly.The four-hole pattern is cut to the mating flange dimensions.
Thin seals extrude under bolt pressure.Selected thickness and broad sealing land distribute compression.
Open-cell materials absorb moisture.Closed-cell EPDM limits fluid uptake through the gasket body.
